Taurus makes good low cost striker fired pistols. I have a 24/7 g2 45acp its excellent, its the only striker fired ive had with a safety and a decocker, great gun for a nice price

You can also get a XD with a external safety. I have never personally seen one. But I did see something about it in my owners Manuel. Kind of pointless tho IMO. It already has a grip safety. I don't think that option is available on any of the M modals tho not sure. I also believe you can get some of the M&P's with external safety's.

Ruger sr series and smith m and ps can also have safeties. The part that makes the 24/7 interesting to me is the safety with a decocking feature. I've never seen that on a striker fired gun

With all due respect if your talking about the Ruger LC9, it's a striker fired as is the Sig P250. So is the Taurus PT 740 and PT 709. The Ruger LCP and Taurus TCP are also striker fired.

No, the LC9 is hammer fired. It's a hidden hammer, recessed into the polymer frame. I had one, trust me. Just look at one in the shop, the back is open and you can watch the hammer as you pull the trigger. Same with Sig. Sig does not make a striker fire. At least that I can recall.

I think I've just about got it covered. Of note, I know there's uncertainty on some of the models (manufacturer's aren't always clear on their websites.). This is OK as it gives me a starting point - I'm not totally against DAO anyway though I'm not a fan of external safeties (except on my 1911).

Muscle memory, training (with a competent, certified instructor), and willingness to be proficient are what is needed.
Some platforms are easy to work with (revolvers, Glocks, XDm's...) while others require dedication

Good points. I'm career military and an outdoorsman who's dedicated to shooting and hunting. My better half is not and will never be. So, for our "mutual use" defensive weapons I conservatively keep complexity to a functional minimum with an emphasis on the 4 rules, accuracy, and very basic tactics.
